Suzuki ECU Diagnostics

Most EFI Suzukis have two diagnostic interfaces to the ECU to allow fault finding to be carried out. One diagnostic interface allows codes to be read by counting the flashes from the Check Engine Light after jumping two of pins in a connector with a wire link.
The second interface uses either a 16-pin OBD2 (J1962) connector or a 12-pin ALDL type connector, this interface can only be read with a scan tool or other specialised hardware. Models equipped with the ALDL connector use a Suzuki proprietary interface known as the Serial Data Link (SDL). Models with an OBD2 connector use SDL, OBD2 (ISO-9141-2) or OBD2 CANBus, this is model specific. Airbag, ABS and transmission controllers usually have there own test connectors.

The Reverse Engineering pages have schematics and other specific details which can be of use when fault finding at PCB level.I also have a good deal of information about the various ICs and other components that can be very difficult to find. A lot of this is not yet published so feel free to ask on the RhinoPower Forum. Please note that the forum is not there to assist with general running problems, the FSM is the best source for that sort of information.
